Course Objectives 

Skills to be learned during this course
 Construct the function or equation that best models the description of a mathematical or practical situation.
 Analyze a functional model to determine information relevant to an application.
 Solve specific problems relating to, but not limited to, compound interest, supply and demand, cost, maximizing revenue and profit, and exponential growth/decay.
 Solve polynomial, rational, radical, exponential and logarithmic equations.
 Use interval and set builder notation to state the domain and range of functions.
 Use algebraic principles of graphing including translations, reflections, expansions and contractions.
 Graph polynomial, absolute value, rational, radical, exponential, logarithmic, and piecewisedefined functions without the aid of graphing devices. Graphs must include any intercepts, holes and asymptotes.
 Solve polynomial and rational inequalities in one variable.
 Evaluate, manipulate and interpret summation notation using properties of sequences.
 Use geometric sequences and series and related formulas to solve problems relating to, but not limited to, annuities.
 Use a scientific calculator to support computations for application problems.
 Given an algebraic expression with rational exponents, rewrite it in simplest form as a product or quotient in which only positive exponents occur.
